    PACKAGE : courier
    SUMMARY : buffer overflow
    DATE    : 2002-11-19 13:11 UTC
    EXPLOIT : local

    - From Debian Security Advisory DSA 197-1 :
    
    A problem in the Courier sqwebmail package, a CGI program to grant
    authenticated access to local mailboxes, has been discovered.  The
    program did not drop permissions fast enough upon startup under
    certain circumstances so a local shell user can execute the sqwebmail
    binary and manage to read an arbitrary file on the local filesystem.
    
    SOLUTION
    
    It is recommended that all Gentoo Linux users who are running
    net-mail/courier-0.40.0.20021026 and earlier update their systems as 
    follows:
    
    emerge rsync
    emerge courier
    emerge clean
